This volume addresses virtual reality (VR) -- a tantalizing communication medium whose essence challenges our most deeply held notions of what communication is or can be. The editors have gathered an expert team of engineers, social scientists, and cultural theorists for the first extensive treatment of human communication in this exciting medium. The first part introduces the reader to VR's state-of-the-art as well as future trends. In the next section, leading research scientists discuss how knowledge of communication can be used to build more effective and exciting communication applications of virtual reality. Looking ahead, the authors explore pioneering approaches to VR narratives, interpersonal communication, the use of 3D sound, and the building of VR entertainment complexes. In the final section, the authors zoom out to view the big picture -- the psychological, social, and cultural implications of virtual reality. Thought-provoking discussions consider important communication issues such as: * How will virtual reality influence perception of reality? * What are the legal issues defining communication in virtual reality? * What kind of cultural trends will this technology encourage?
